W. Lu et Cd. Gong, LOCAL-MOMENT ANTIFERROMAGNETIC SPIN FLUCTUATIONS AND THE NORMAL-STATEPROPERTIES OF HIGH-T(C) CUPRATES, Physica. C, Superconductivity, 224(1-2), 1994, pp. 75-78
A phenomenological model is proposed to investigate the two-dimensiona
l spin fluctuations of local-moment antiferromagnets self-consistently
. The nuclear-magnetic-resonance relaxation rate and the electrical re
sistivity due to spin fluctuations are calculated. The results in the
quantum critical regime just explain the anomalous behavior of high-T(
c) cuprates in the normal state. Finally, the effective dynamical susc
eptibility in the presence of randomness is supposed.
